Homes in West Glamorgan
Housing in Wales ranges from terraced streets in the valleys and older industrial towns to stone-built homes in rural areas and modern estates around the cities.
What does a garden annexe involve?
A garden annexe is a separate single-storey building in the grounds of a house with its own bedroom, bathroom and kitchenette, used by family members as part of the main household. Unlike a garden office, an annexe that people sleep in normally needs planning permission and full building regulations approval.
- Design and planning application
- Brick, block or timber-frame structure
- Heating, hot water and electrics
What will a garden annexe cost?
Typical ranges for garden annexes. Ground conditions, access and specification move the final figure, which we fix in writing before work starts.
| Garden annexes | Guide price incl. VAT |
|---|---|
| Standard specification | £2,400 to £2,900 per m² |
| Good specification | £2,900 to £3,400 per m² |
| High specification | £3,400 to £3,900 per m² |
Planning and building rules in West Glamorgan
Welsh projects need planning clearance from the council under Welsh rules, building regulations approval under the Welsh approved documents, and party wall notices where the work affects a neighbour’s wall or foundations.
In Wales an annexe with sleeping accommodation needs planning permission, usually with a condition tying it to the main house.
What should West Glamorgan homeowners check first?
- Drainage may need a pump if the garden falls away from the sewer.
- A level threshold and wider doors make the annexe suitable for later life.
What happens after I enquire?
- Send us the details. Give us a postcode, a rough idea of size and some photos, by phone, form or the guide price tool.
- Free site visit. We measure up, look at access, drains and the structure, and talk through options and budget.
- Design and fixed price. You get drawings and a written price for the agreed specification before anything is ordered.
- Build and hand over. Our teams build to the programme, building control inspects, and you get the completion paperwork at the end.
What people ask before starting
Do I need planning permission for a garden annexe?
Usually yes, because people will sleep in it. Outbuilding permitted development does not cover living accommodation.
Can you make it wheelchair accessible?
Yes. Level access, wider doors and a level-access shower can be designed in from the start.
Can you visit a house in West Glamorgan to quote?
Yes. After a short call we arrange a site visit to measure up and agree what the design needs to do, then send a written price.
